Mitt Romney today unveiled the endorsement of former Sen. Mel Martinez, who will serve as chair of the campaign’s National Advisory Council, according to a release. Interestingly, Martinez, the first Cuban American elected to the United States Senate, was a primary sponsor of 2006’s failed comprehensive immigration bid that faced withering criticism from conservatives.

Along with Senators Dick Durbin, Harry Reid, Patrick Leahy, Joe Lieberman and Russ Feingold, Martinez cosponsored the DREAM Act of 2009, which closely tracks the Texas measure that has become of late Romney’s primary target.

One can debate whether or not Perry’s Texas policy was prudent. But regardless of where one comes down on that, the notion that Mitt Romney is a clear alternative to Perry on the immigration issue seems increasingly laughable.
